The **de Broglie equation** is an equation used to describe the **wave properties** of matter. The **de Broglie equation** is as follows:

**Where λ **is** **the wavelength of the particle **(m)**,

**h **is the Plank’s constant **(6.626 x 10 ^{-34} m^{2 }kg / s)**

** m** is the mass of the particle **(kg)**

**v **is the speed of the particle **(m/s)**

An alpha particle (mass = 6.6 x 10 ^{−24} g) emitted by a radium isotope travels at 3.4 x 10^{7} ± 0.1 x 10 ^{7} mi/h. What is its de Broglie wavelength (in meters)?
